If you are also a sports enthusiast, you should exchange your sports views with each other. Generally, people who like sports will like learning. If you happen to be fitness enthusiasts, you can make an appointment with each other to exercise together, which will not only exercise but also enhance friendship. This is a great opportunity.
If you don't like sports and exercise, then I suggest you talk to your partner about her fitness experience. Fitness people are very willing to share their exercise experience with others. In this process, you can learn a lot of fitness knowledge, and you can also leave a good impression on each other that you love learning. Maybe you will become a fitness enthusiast and change your lifestyle from now on!
Anyway, come on!
